In a fight for your life, you use what you brung or have at hand. If bare hands are all you have then that is what you use.

My one experience was with an armed intruder into our Condo at Squaw Valley, CA. The guy entered the bedroom from an outside balcony. I bull rushed him under the weapon and pitched him into a snow bank from the second floor.

Heavy crockery plates are excellent Frisbee.s. They also do an amazing amount of damage when they strike a body.

You need to always be aware of potential adversaries. Conversely you need to look for potential weapons as you check for exits.
